Great! this will be your final and most noted difference in the uncorking process. The pipe enables the engine to breathe freely, and compliments your intake mods. I ran rejetted and airbox open and smog gone with a stock pipe and yea it was okay, but man when I installed the white brothers E2 it really came alive, strong freight-train pull from idle to seemingly infinity... plus it sounds "healthy". Good to hear! What did you end up with for jets?
